Re: T&T Spirit – Crankshaft replacement – Caribbean Shipyards, Trinidad 2018

GSE provided a specialist team of service engineers to repair failed ‘Ruston RK 270’ main engines onboard the T&T Spirit operated by the Port Authorities of Trinidad and Tobago.

Following major in-service main engine breakdowns in June 2017, the Vessel ‘T&T Spirit was taken out of service to complete breakdown repairs to its Stbd Outer & Port Inner main engines.

Extensive repair works were carried out to replace the Crankshaft on the Stbd side main engine and carry out specialist In-situ repair to the Entablature block and Crankshaft on the Port side main engine.

Working in conjunction with OEM Suppliers, the Vessel was returned to service in April 2018, following DNV acceptance trails.

Minor overhaul of Jenbacher 316, for Cory Environmental Ltd at Highfield Landfill site, January 2017

January 2017, GSE completed a minor overhaul of a Jenbacher 3 Series generator, installed at Highfield landfill site, operated by Cory Environmental ltd.

During a 5 day shutdown period, an overhaul schedule was undertaken that included removal of cylinder heads, pistons, connecting rods and cylinder liners. Along with removal of the turbocharger, aftercooler and crankshaft damper.

The original set of connecting rods was re-conditioned, to replace SE bushes and re-certify running tolerances. New pistons and ring packs were installed onto original connecting rods and re-fitted with new LE bearings, complete with a spare set of re-worked cylinder heads.

Finally the original Turbocharger and Aftercooler were re-fitted to the engine following subsequent overhaul. Finally a new OEM supply crankshaft damper was assembled to the engine.

On completion of the rebuild, the engine was run-up to complete initial bearing runs and gradually stepped up at loaded increments up to 400kw to verify performance.

YLEM Energy Ltd - Workshop overhaul of 8 Cylinder, Perkins 4008 Series LFG powered engine

In December 2016 GSE commenced a major workshop overhaul for YLEM Energy Ltd of an 8 Cylinder Perkins engine. The engine was due to be re-located and was due a major 70’000 hour overhaul.

The crankshaft was removed for specialist repair, due to undersize main and crankpin journals. The crank was ground throughout to – 0.25mm and refitted with OEM bearings and replacement damper.

The original cylinder heads were reworked, replacing valves, seats and guides. Connecting rods, cylinder liners and gear driven pumps were replaced with new OEM parts.

The workshop rebuild was completed with the engine lubricating oil system flushed on completion, along with a full re-spray, prior to being transported to Brook Hill Landfill site in Flintshire.

On completion of the rebuild, the engine was run-up to complete initial bearing runs and gradually stepped up at loaded increments up to 400kw to verify performance.
