Engineer’s Report (Bme 057/ Issue 3)

Providing safety through mechanical excellence

Introduction Bartech Marine attended Isla S to carry out a complete overhaul of the main engine. This was completed whilst the vessel was in dry dock at Dunston Engineering in Hull, as part of its planned schedule of maintenance.

Work Carried Out Bartech arrived on site on the 2nd of January. All tools and spares were unloaded into a container on site. Unfortunately, due to the site contact and shipyard personnel not arriving until the 3rd we were unable to start work until the following day. The following items were removed from the engine for inspection and overhaul at Bartech: • • • • • • • • • • • • • • • •

Turbo charger 6 x Cylinder heads Governor Fuel pumps Injectors Rocker Gear Pistons Connecting rods Crankshaft Oil cooler Intercooler 2x fresh water pump Fuel booster pump Coolant pump Oil pump Liners

As the engine was dismantled, external components such as the air and water manifolds were chemically cleaned and visually inspected. The rubber seals between the coolant rail and exhaust elbows were found to be hard and distorted so these were replaced.

Turbocharger The turbocharger was removed from the engine and sent to Bartech’s workshop in Colchester. The lagging surrounding the exhaust was removed and found to be in poor condition (Figure 1 & 2). A recommendation was made to the customer to replace the lagging following the rebuild, this was rectified locally by the client.

The turbocharger was then completely dismantled and chemically cleaned. The turbine and compressor housing along with the central housing was inspected for signs of cracking and scuffing from the rotor assembly – none were found. The rotor assembly was cleaned, and crack detected prior to being sent for dynamic balancing. The nozzle ring was cleaned and inspected and evidence of cracking was found (Figure 3). A new nozzle ring was ordered and fitted.

Figure 4 Completed turbo

Once the rotor assembly was returned from balancing the turbocharger was rebuilt using a comprehensive overhaul kit which included all new bearings, seals, assembly screws and stainless-steel tab washers. The rotor assembly end float was measured and was within new manufacturer limits. The completed assembly was loaded onto a pallet for transportation to the vessel (Figure 4). Governor The governor was removed from the engine (Figure 5). This was then sent back to Bartech’s workshop for overhaul.

Figure 5 Governor removed

Figure 6 Governor on test prior to overhaul

The unit was placed on the test rig (Figure 6) and allowed to run for 15 minutes to warm through before any figures were taken. It was noted the oil pressure was below the recommended pressure of 150psi. A full set of figures were taken on the up-ward pressure range. The hysteresis was checked on the downward pressure range and found to be varying. This is an indication of internal component wear or possibly worn flyweight toes which alters the pre-set balancing port position.

Figure 7 Cleaned parts ready for reassembly

Figure 8 Wear marks on drive shaft

The unit was fully dismantled and the casting placed in paint stripper to remove all old paint and oil deposits. The casting was checked for any wear on the bores and none was found. All internal components were washed in a solvent based cleaner to remove all traces of oil prior to inspection (figure 7). All the internal parts were coated in a black lacquer. This is normally an indication of wear on the drive shaft where the seal locates. An inspection of the internal components found the ball head flyweight toes were worn as expected and there was a groove in the drive shaft in the area where the oil seal is located (Figure 8).

Figure 10 Hydraulic jacks in use

The governor was then placed onto the test rig and filled with clean engine oil. The governor was allowed to warm up to 50°C. The governor’s speed and pressure are stamped on the unit’s data plate but there was no set point for the droop, so the unit was set to the droop figure as was found upon arrival at the vessel. Speeds were checked and adjusted in accordance with both pre-test figures and those on name plate. Hysteresis was checked and found to be within 1 rpm. The emergency manual speed control device was refitted and the oil drained. The unit was then bolted to a transport stand for return to the vessel. Cylinder heads The cylinder heads are mounted with hydraulically stretched studs. This required a special jacking system to be fitted to each stud to allow the nuts to be removed (Figure 10). It was found upon removal of the cylinder head nuts that one of the studs was badly corroded which required the nut to be removed from the stud using oxy-acetylene equipment (Figure 11 & 12). During this process the engine was protected as much as reasonably practicable to avoid contamination. The cylinder heads were then removed from the engine using chain blocks.

The six-cylinder heads were transported to a local workshop where they were dismantled and chemically cleaned. The valve springs, collets, rotor caps and valves we also chemically cleaned. Upon inspection of the cleaned components it was found that eleven of the valve rotator caps had excessive wear. The exhaust valves and valve seats were found to be heavily pitted. These were re-cut (Figure 13) and lapped before being measured. All valves were found to be within the manufactures maximum recommended wear tolerances. It is recommended that the valves be replaced at the next overhaul. One of the cylinder head core plugs had previously had a poor repair and was replaced. After the rebuild of the cylinder heads, the water ways were pressure tested to twice operating pressure. All were OK. On the cylinder heads there are cylinder relief valves which should activate at 200bar. Each valve was tested and was found to be cracking at the incorrect pressure. All were at 100bar or less. All valves were replaced with new items pre-set to the correct pressure by Wartsila OEM.

The cylinder head stud & nuts were difficult to remove due to paint and corrosion. Five studs were replaced due to corrosion (Figures 14). There is evidence that there has been considerable force put on the studs as they are stretched to 90% of their elasticity when fitted. The cylinder block stud holes have signs of corrosion in the block and threads. The stud hole threads were cleaned out using a thread tap. Cylinder Block Cylinders 1 & 2 were found to require machining of the landing surface as they were out of tolerance and visually in poor condition due to being heavily corroded. Cylinders 1 & 2 were machined, and spray metal welded. The areas not requiring work were environmentally protected using sheeting to eliminate any air born particles from the bead blasting, metal spraying and machining processes (Figure 15 & 16). Once machining was completed the block faces were cleaned of all oil, greave and paint residues and prepared for the re-assembly using the overhauled components

Figure 16 Machining complete

The e bores on cylinders 3, 4, 5 & 6 were all pitted, but we believe they will seal correctly without issues. Fuel Lines The fuel lines from the pump to the injector were removed and found to be in poor condition. The nipples were badly worn, and some threads damaged. The fuel lines were replaced (figure 17 & 18).

Figure 20 Broken plunger spring

One fuel pump plunger spring was found to be broken (Figure 20) and the remaining five springs were found to be in poor condition and were replaced. One control sleeve was also found to be cracked, this was replaced. The ends of the control rods were worn, and these were machined to bring them back into manufacturers tolerances. The pumps were rebuilt, replacing the plungers and barrels. We have also fitted a replacement control sleeve, six plunger springs and all new joints and gaskets. The pumps were pressure tested to ensure no leakage between the fuel gallery and the engine oil side, no leaks were identified. They were set up on the test rig and tested to specification. All pumps performed ok.

Injectors These were removed and returned to Bartech for testing. The injectors were set up on the test rig and tested. The spray patterns and cracking pressures were not within the OEM specifications with the nozzles hosing and the pressure releasing too early. New nozzles were sourced and a full rebuild of each injector was carried out. They were then retested and the nozzle opening pressures set to OEM specification, all injectors passed ok. Rocker Gear The rocker gear was removed and taken to a local workshop where it was dismantled, cleaned and measured by a Bartech engineer with assistance from the workshop engineers. All bushes were replaced with new. Pistons The pistons were removed along with the connecting rods using chain blocks (Figure 21 & 22). All pistons were chemically cleaned and then visually inspected for wear and damage. The ring grooves were measured prior to chemical cleaning, all were within OEM tolerances and gudgeon pin bores were dimensionally checked with a bore gauge. All pistons had their respective piston rings removed.

Figure 21 Piston removed

Figure 22 Connecting rod under repair

Connecting rods The connecting rods were removed and cleaned. The small ends were measured and found to be out of OEM specification, so new bushes were fitted. The large end was then measured and found to be out of tolerance and oval. Bartech recommended that the connecting rods be re-machined to reduce costs rather than replacing them. Although this affected the total time of the overhaul, significant cost savings were achieved.

connecting rods were packed & returned to Bartech for overhaul. Following the machining, the connecting rods were re-measured and shot peened. They were then crack-detected, and no issues were identified. Crankshaft Due to the size of the engine and where it is situated, it was not possible to remove the crankshaft. To check the serviceability of the crankshaft, one main bearing cap was removed and the bearing and crankshaft journal were inspected for wear. Nothing of note was identified. Oil cooler/ filter assembly The oil cooler was removed from the vessel (Figure 23) and taken to the local workshop for overhaul. The unit was dismantled and then chemically cleaned. The unit was then rebuilt using new seals, and pressure tested to twice the working pressure.

Figure 23 Oil cooler removed

Figure 24 Intercooler under repair

Intercooler Upon removal of the intercooler it was noticed that there was an oil/water mixture forming a mayonnaise type substance inside the intercooler cover (figure 24). The intercooler was chemically cleaned, inspected and rebuilt. It was then pressure tested and no issues of note were identified. Our conclusion for the mayonnaise like substance is that this was caused by a slight oil mist in the intake system, which then condensed during cool down periods. This is normal and is not of concern.

Drive gearbox The ancillary drive gearbox, which drives the two fresh water pumps, fuel booster pump and the oil pump was removed for overhaul (figure 25 & 26). The gearbox was dismantled, and cleaned on the vessel. The bearings although ok were replaced as per the OEM service schedule for an engine that is undergoing a full overhaul. With the gearbox dismantled it was discovered that there was substantial damage to the water pump drive gear output serrations. A new gear was sourced and installed. The mating services were cleaned and the gearbox was rebuilt and re-installed.

Figure 26 Gearbox removed

Water pump The water pump was removed from the ancillary gearbox and sent to the workshop for overhaul. The unit was dismantled and chemically cleaned to allow for further inspection. The main water pump driveshaft splines were found to be worn and required replacement. Once the new shaft arrived the pump was rebuilt using all new bearings, seals and gaskets. Once the rebuild was complete the unit was then pressure tested to 30psi using 50/50 mix coolant for a total time of one hour. No leaks were identified. Fuel Booster Pump The fuel booster pump was rebuilt on site. The unit was dismantled and inspected for wear. The pump was then cleaned. There were no issues of note identified so the unit was rebuilt using new bearings and gaskets. The unit was then re-refitted. Sea Water Pump The sea water pump was removed from the ancillary gearbox and sent to the local workshop for overhaul using standard overhaul materials. The unit was dismantled and chemically cleaned to allow for further inspection. The pump was in generally good condition and no additional parts were required. The pump was rebuilt using all new Vat No: GB 4635797 08 Tel: +44 (0) 1206 791552 Company No: 02154196 Fax: +44 (0) 1206 225241 Registered Office: Email: [email protected] Unit D E & F, Chandlers Row, Web: www.bartechmarine.com Colchester, Essex, CO1 2HG Lapline Ltd trading as Bartech Marine.

bearings seals and gaskets. Following the completion of the overhaul the pump was pressure tested to 30psi using 50/50 mix coolant, for a total time of one hour. No leaks were identified. Oil Pump & Oil Supply Lines Following the removal of the oil pump from the engine a visual inspection was carried out and no excessive wear was found in the drive gear or its corresponding drive. The oil pump was completely dismantled, all parts washed then arranged for inspection against manufactures limits and dimensional requirements. All oil supply lines were separated, washed and checked for damage, no damage was found. The bush bores were checked for scoring and none were identified. The rotor back lashes and end floats were also checked, and no issues were identified. The unit was assembled using gaskets supplied in the manufactures overhaul kit and the pump checked for free rotation following the completion of assembly. Liners The liners were removed using a lifting plate along with a chain block. This took a considerable amount of time due to the condition of the liners. There was a thick sludge inside the water jacket, it was apparent that the liners had been leaking for some time & there was visible corrosion around the liner bores (Figure 27 & 28). The liners were replaced (Figure 29 & 30).

Engine First Run The engine was filled with water to check for leaks. The water pipes from the exhaust were found to be leaking so the flex master couplings were removed and rubber hose fitted with jubilee clips. The water was then drained, and the engine was refilled with coolant. Once completed, the engine was then filled with oil, this took a considerable amount of time due to the ambient temperature and the oil being viscous. The fuel system was bled and had an initial setup carried out. An engine start was then attempted. Unfortunately, one of the air start valves was firing at the wrong time. Upon further inspection it was found to not be sealing sufficiently and so required replacement. The decision was then made by MacDuff to replace all the air start valves. With the new air start valves fitted another attempt to start the engine was made. The engine took longer than expected to fire due to being very cold. The engine pre-heat system fitted to the engine is not very efficient and was not heating the engine effectively. The engine was run at 600 rpm for 10 minutes to check for leaks. The stop signal was working correctly, and gauges were functioning. The engine was then run up to operating speed over one hour with no load. The engine was hunting and No.6 cylinder was 40 degrees lower than the other cylinders. To ensure the gauge was reading correctly, this was swapped from another cylinder, with the same results. Due to the engine not being on load this was to be expected as all fuelling adjustments need to be made with the engine operating under load. There was also some evidence of hunting of the engine on initial start-up, this was due to there being a small amount of air in the governor and the engine oil being very cold and viscous. Once the engine had warmed up and the oil thinned down, the engine revs stabilised and held steady. During this run it was found that the ancillary drive gearbox had an oil leak from the oil seal, this required the gearbox along with the ancillary components to be removed and resealed. The engine was then run again, and the oil leak had been resolved.

Once the initial running test had been completed there were several days wait while other works were carried out on the vessel before sea trials could commence.

Sea Trial The sea trial and run in procedure was as follows: • • • • •

One hour and a half with 20% load One hour and a half with 40% load One hour and a half with 60% load 30 mins with 30% load whilst the dredge was dropped One hour and a half with 100% load

The engine test sheet is attached at the end of this report. The engine was fully monitored during the test and when the test was at the 100% load a set of peak combustion pressures were taken. OEM specification states that you should have no more than 10bar difference between cylinders. The highest was 117.7bar and the lowest was 111.9bar which were within specification. No adjustments to the fuel racks were necessary. The following Amots were also checked and adjusted; • • • • • •

HT water temp set to 91°C LO temp set to 83°C Charge air temp set to 60°C Low rpm LO pressure set to 0.62bar High rpm LO pressure set to1.45bar HT & LT water pressure set to 0.3bar

The overspeed trip was also checked and adjusted to 920 rpm and then tested. No issues were identified. Previously the engine had hunting issues and erratic exhaust temperatures. As the engine reached full temperature these issues disappeared. The engine test run sheets can be seen at the end of this report.

Outstanding Actions None at time of sea trial completion.

Recommendations Continued servicing should be carried out in line with the manufactures recommendations. Regular oil samples should be taken to monitor engine condition.

Cylinder Head Test Sheet (Bme 018J3 / Issue 6)

Providing safety through mechanical excellence

If replacing valves seats it is important that both the valve seat bore and the valve seat insert diameter are measured with regard to the interference fit. If available please refer to literature for details on dimensions, for example for a Paxman YJ, dimensions of the valve seat bore is in the ops & maint book and there are drawings for the inlet and exhaust inserts, having looked at these it appears that there is around a 0.003” to 0.005” interference, if you have no literature use this as a guide.
