The latest Mooring Equipment Guidelines (4th Edition) issued by Oil Companies International Marine Forum (OCIMF) MEG4 puts forward the new requirements for mooring equipment arrangement and ship-to-ship (STS) transfer. The main influence of the new requirements on the design of the mooring arrangement of oil tankers has been analyzed by interpreting the relevant new requirements in combination with the practical designs.The related research contents can provide reference for the subsequent design of similar ships.

“XUE LONG 2” is the first polar icebreaking research vessel built independently in China. The vessel has the characteristics of the transport ship, ice breaker and scientific research ship. This article gives a general description of the scope of the outfitting design, design principle and equipment configuration. It focuses on the analysis of the key design points, including the typical common technical problems. The summary of the relevant experience can provide reference for the design of the new polar research vessels or the similar projects in the future.

In recent years, more and more public service ships and scientific research ships have been built in china. Most of them will be equipped with helicopter landing platforms and even hangars due to the particularity of such ships. However, there is no common design rule for the helicopter landing platforms and hangars of such ships, resulting in the non-unified standards and rules adopted in the design. The current relevant civil and military rules for the design of the helicopter landing platforms and hangars are compared and analyzed in view of the above situation. The applicability of the design rules is discussed for the helicopter landing platform and the hangar of a full-scale ship. It can provide reference for the future similar designs.
