PrimeShip-GREEN/ProSTA ver.ISO is a software that allows
users to analyze ship speed correction at progressive speedtrials taking into account factors such as wind, current, wave,
shallow water, displacement, water temperature and water
density in compliance with ISO 15016:2015, and derive a ship

speed for Energy Eﬃciency Design Index (EEDI) calculation.

Software for Assessment of Minimum Propulsion Power◆Easy to assess the minimum propulsion power
to maintain the manoeuvrability in adverse
conditions according to the “minimum propulsion
power guidelines”◆Stand-alone software base on Microsoft Excel◆User-friendly interface◆Auto-generation of output results and ﬁgures forclass approval
This software is intended to conduct assessments of required
minimum propulsion power in adverse conditions for bulk
carriers, tankers and combination carriers with the size ofequal or more than 20,000DWT by means of methods
deﬁned in MEPC.1/Circ.850/Rev.3 of IMO “ GUIDELINESFOR DETERMINNING MINIMUM PROPULSION POWER TO
MAINTAIN THE MANOEUVRABILITY OF SHIP IN ADVERSECONDITIONS”.

Main Functions◇Assessment Level2 in the guidelines is available.
◇This assessment procedure is based on theassumption that, if the ship has suﬃcient installed
power to move with a certain advance speed inhead waves and wind, the ship will also be able
to keep course in waves and wind from any otherdirection. It is necessary to input self-propulsion
factors, aerodynamic resistance, added resistance,etc. for the assessment.
◇Easy to conﬁrm the level of achievement since
the assessment is conducted just at the point
where the added resistance due to wind andwaves is at maximum.

Structure of the system
Input◇Shipʼs principal particulars◇Self-propulsion factors◇Frontal and side windage area of hull andsuperstructure◇Propeller open water characteristics◇Torque-speed limitation curve of the engine
provided by the engine manufacturer

Ship Recycling Management◆Inventory development software compliant withthe Ship Recycling Convention* requirements◆Exchange Material Declaration (MD) data electronically
PrimeShip-GREEN/SRM is an essential software tool for thedevelopment of the Inventory of Hazardous Materials (IHM)

required for all ships greater than 500GT by the Ship Recycling
Convention adopted in May 2009.

PrimeShip-GREEN/SRM allows suppliers and shipbuilders toexchange information electronically to reduce paperworkrelated to IHM development.

In order to substitute the client /server based IHM development software: PrimeShip-INVENTORY,
NK has developed the web-based software “ PrimeShip -GREEN/SRM ”. Utilizing cloud computing,PrimeShip-GREEN/SRM will certainly improve the productivity of users.

【For Suppliers】
PrimeShip-GREEN/SRM enables suppliers to consolidate the responses for shipbuildersʼ requests tosubmit Material Declaration and Supplierʼs Declaration of Conformity. In addition, suppliers can post
their MD on MD Library so that the shipbuilders can ﬁnd the MD by themselves.

【For Shipbuilders】
PrimeShip - GREEN/ SRM allows shipbuilders to develop the IHM (Excel format) by requesting
MD/SDoC to suppliers in the system and setting locations for MDs containing Hazardous Materials.
PrimeShip-GREEN/SRM eliminates the need to post MD data and automatically calculates the amountsof Hazardous Materials at each location.

Concept of PrimeShip-GREEN/SRM

Screenshots

Ship Recycling Convention
Ship Recycling Convention* was adopted by the IMO in May
2009. Once the convention enters into force, all ships
500GT and greater, excluding those scrapped or recycled
in their ﬂag states, will be required to carry an Inventory ofHazardous Materials on board the ship.

IHM Development for New Ships
Shipbuilders develop an Inventory by the following steps:<Step 1> Record submitted Material Declaration (MD) and Supplierʼs
Declaration of Conformity (SDoC) for all procured products.
<Step 2> Screen all products containing Hazardous Materials
above the threshold levels.
<Step 3> Identify the location of these products and calculate
the amounts of Hazardous Materials at each location.
<Step 4> Prepare properly formatted Inventory.
