ENGINEERING
The nowadays Yacht Owners require Silence and Comfort as a standard onboard their Yacht. I remember very well, stated Sjaak van Cappellen founder of Silent Line, that in the early 1980’s we worked hard to achieve noise levels between 60 – 70 dB(A) while cruising, nowadays the requirements are between 40 – 45 dB(A) while cruising and close to 25 – 30 dB(A) while at anchor. We achieved this by means of comprehensive engineering studies, starting in an early stage of the project, however it is not an easy task to achieve.
PUSHING THE BOUNDARIES:
As Silent Line we are honored and proud that we signed a contract with Dynamiq Yachts for the brand new full aluminium GTT160-01 project in which we must achieve contractual stunning low noise and vibration levels knowing:
TRANSIT CONDITION:
80% MCR of both main engines | generator set running and HVAC operational
Guest areas:
42 dB(A)
Owners’ stateroom:
36 dB(A)
Salon and Dining area:
45 dB(A)
Vibration levels not to exceed 0.3 mm/sec in accommodation areas
ANCHOR CONDITION:
Generator set running and HVAC operational
Guest areas:
30 dB(A)
Owners’ stateroom:
30 dB(A)
Salon and Dining area:
40 dB(A)
Vibration levels not to exceed 0.1 mm/sec in accommodation areas
To my knowledge, stated by Sjaak van Cappellen CEO of Silent Line, this has never been achieved onboard an aluminium Yacht in this size. We achieved similar results onboard the 37XP Numarine Explorer Yachts however these Yachts have a steel hull which is a benefit from noise and vibration control.
