ENGINE ROOM REFITS
This includes regular servicing of the main engines by official manufacturers agents. In some cases the W6 service requires the complete removal of the main engines and transportation to the agent's workshop. This often requires the cutting of an access hole in the hull and removal of all the necessary pipe work and services in order to take out the engine. Consequently any damage to the vessel's superstructure is eliminated by removing parts through the temporary hull access point.
Depending on the usage of a yacht, the generator life span is finite and often dictated by how much time the yacht spends connected to shore power. Within 10 years it is very likely that a complete rebuild will be required. Most clients at this stage plan to replace the old units for new as technological improvements of engines over time; consumption, vibration, noise levels etc make it the far more economical option.




M.Y. Paraiso
The combination of a V-drive system and the singular, limited height of the hull design, was one of many challenges during the extraction of the older MTU 16V 538TB82 engines through a hull opening. The preliminary study of the engine room’s dimensions and special layout was crucial in order to choose the less invasive strategy and adapt the brand new MTU 12V 4000 M53R engines. The shaft lines have been renewed and the 5 blade propellers were fitted instead of the former 4 blade props. The yacht was equipped with new exhaust systems, water makers, air-conditioning plant, vacuum systems and gearbox. All these changes entailed a new electrical circuit concept as well as the complete renewal of sanitary, fuel and seawater piping.

M.Y. Cheetah Moon
After 25 yrs of service, M.Y. Cheetah Moon is undertaking a major engine room refit, replacing the main engines and generators. This decision was not taken lightly, so after a Lloyd's survey the conclusion was that refitting newer equipment was not only financially more viable but also savings in weight and consumption would eventually benefit the running of the vessel. Replacing the compressed air starters for electric starters on the main engines helped in this saving and finishing touches such as a new silent exhaust system coupled to a new engine room isolation system will also provide advanced comfort for her passengers. Other modifications included a new piping system and an updated bow thruster.
