General information
One of the challenges in the quantification of the seakeeping performance is establishing acceptable level of motions, accelerations, forces, water on deck etcetera. What should be the criteria in order to ensure a comfortable and even more important a safe ship?

The MARIN seakeeping knowledge group evaluates the seakeeping performance in their facilities and with dedicated numericall tools. The list below shows a number of regularly applied seakeeping standards:
- NordForsk (ISBN 87-982637-1-4, 1987), Criteria for merchant ships, criteria for amongst others; vertical and transverse accelerations, roll, slamming and deck wetness
- Stanag 4154 (NATO, 1998), Criteria for naval ships, Criteria for amongst others; roll, pitch, vertical and transverse accelerations, MII, MSI, slamming, propeller and sonar emergence, deck wetness and helicopter operations
- Roll at anchor for motor yachts (internal MARIN study, 2006), Evaluation of stabilised and unstabilised roll motions at anchor for a large number of motor yachts
- Motion induced interruptions (Graham, 1990), MII gives an indication of the number of events in which a standing person will look for support in order to maintain balance
- Motion Sickness Incidence (O’Hanlon and Mc Cauley, 1974), MSI gives fraction of unadapted people who would suffer from seasickness within 2 hrs
- Trailer Lashing (Dallinga, R.P., 1994), Criteria for lashings to prevent sliding/tipping of trailers
Facilities & Tools
Not all aspects of the seakeeping behaviour can be quantified numerically, but could be addressed by tests in the following MARIN facilities:
Not all aspects of the seakeeping behaviour can be quantified numerically, but could be addressed by tests in the following MARIN facilities:
- Seakeeping & Manoeuvring Basin: seakeeping and manoeuvring tests
- Offshore Basin: offshore tests including waves, wind and current
- High-speed Basin: tests at high froude numbers (ahead and astern wave conditions possible)
An operability assessment could be performed with the following tools:
WASCO: Workability analysis of ships and constructions offshore
GULLIVER, a ship designers’ edge
SafeTrans: Safe design and operation of marine Transports
GULLIVER, a ship designers’ edge
SafeTrans: Safe design and operation of marine Transports
Experience
In almost all our projects regarding seakeeping, test and/or calculation results are compared to seakeeping standards in order to judge the performance.
