GOLTENS ENGAGES WITH ITS
PARTNER TEKOMAR TO
PRESENT AN ALTERNATIVE
TO THE MAKER
DAMAGED EXHAUST ACTUATOR CAM
REPLACEMENT ON A SULZER 4RTA-58
During a voyage from Djibouti to Sharjah, a 15,000 DWT
cargo ship owned by Ethiopian Shipping Lines experienced
an unfortunate failure on the vessel’s camshaft and severe
damaged was discovered on unit 2’s exhaust actuator cam.
With no alternative, the ship’s crew isolated this unit and
continued sailing with severe vibrations, crossing dangerous
waters at half of its normal sailing speed.
The maker boarded the vessel at anchorage and was not
able to provide in-house solution due to availability of a
Specialist. The owner contacted Goltens to attend the vessel,
perform an inspection and propose a solution.
Goltens acted immediately by providing a team of 1 Service
Engineer and 3 technicians to start dismantling. The
following day, the camshaft sections were out for the actuator
replacement. Goltens engaged a specialist from its partner
TEKOMAR with specialized knowledge of this type of repair.
During the course of inspection, the team discovered the
actuator cam on unit 3 also required replacement due to
aging and material fatigue.
REPAIRS CONSISTED OF:
• Replacement of actuator cam unit number 2
• Replacement of actuator cam unit number 3
• Inspection of fuel linkages
• Inspection of balancer
RESULTS:
Within 48 hours, the engine was operationally tested with
starting kicks both in ahead and astern directions without any
problems.
The vessel was returned to operation and sailed on time for
her to attend to her commitments with high praise for both
Goltens’ and Tekomar’s capabilities and response.
