ShipCEMS

Monitor your marine exhaust gases

ShipCEMS is designed to monitor your marine exhaust flue, ensuring that compliance with MARPOL Annex VI can be confirmed in ports, in international waters and emission control areas (ECA/SECA). Inspired by environmental concerns, ShipCEMS is designed to measure, analyse and report traces of SO2 and CO2 in wet marine exhaust flue. Monitoring of NOX, O2 or other gases are available as options.

As the flue gases are dirty, with a high content of soot, trace components can easily be lost before arriving at the analyser instrument. The ShipCEMS design solution is based on a heated sample treatment throughout, without needing to introduce chemicals. This assures that the true composition of the exhaust flue is measured.

ShipCEMS is designed for unmonitored, continuous operation. The user interface is simple and intuitive, with a limited number of operations necessary to use the system. The analysing technology is based on the use of non-dispersive infrared detectors (NDIR). This is a simple and robust measuring technology, being the industry standard when used in demanding applications.

ShipCEMS can monitor up to four processes simultaneously. One sample probe and one sample conditioning cabinet must be installed for each exhaust stack or combustion process to be monitored. Only one analyser cabinet is required, taking care of the necessary sample stream switching.

In the ShipCEMS portfolio you find these products

ShipCEMS Classic

Exhaust gas emissions from ships are subject to constantly stricter international, national and local regulations defined by the International Maritime Organization (IMO). The global 0.50% sulphur cap from 2020 improves the climate. Stricter limits are already in place in Emission Control Areas (ECAs) in Europe and the Americas, and new control areas are being established in ports and coastal areas.

ShipCEMS Compact

Exhaust gas emissions from ships are subject to international, national, and regulations defined by the International Maritime Organization (IMO). ShipCEMS COMPACT is your guarantee of documented compliance.

Fuel Gas Analyser

Norsk Fuel Gas Analyser is your guarantee of a real time analysis of your fuel gas. In less than 30 seconds you will know your fuel calorific value and methane number together with full gas composition

High-Level & Overfill Alarm System

Vimex Overfill alarm systems are designed for optimal operation and trouble-free service life. Level switch NOR 4082 has a titan float but can also be delivered in acid-proof material. The overfill alarm is extremely durable and capable of handling most cargoes including LPG and LNG.

Marine High-Level Alarm Switch

Vimex High level alarm switches are designed for optimal operation and trouble-free service life. Level switch NOR 4082 (S, DI, TI) has a titan float but can also be delivered in acid-proof material. The overfill alarm is extremely durable and capable of handling most cargoes including LPG and LNG. On the new generation switches the lifting rods can test each alarm separately.

NMVOC

During loading, storage and transportation of crude oil and liquid hydrocarbon products, will volatile organic compounds (VOC) boil off. To recover valuable energy is the heavy fractions of VOC are liquified in a vapor recovery unit (VRU) to LVOC. The LVOC is used as a fuel adder in machinery or boilers.

Digital Pressure Calibrators

A range of handheld pressure pumps for the calibration instruments. The pumps are durable and suited for the demanding environments on board ships and in the offshore/Industrial fields. All pumps are available in a kit configuration with case and all necessary fittings, hose and adaptors.

Digital Pressure Gauge

The PM205, supplied with calibration certificate, will serve as a valuable first line pressure calibration and measurement instrument. The PM205 is a microprocessor controlled, accurate and versatile digital pressure measuring and calibration instrument with integrated fast peak-, max.- and min.- function.

Temperature Calibrator

The calibrator have been designed to maintain high accuracy and stability under the most severe conditions. The portable calibrators are used on offshore rigs and by leading ship owners world-wide.

Marine Test Case

Our Mini test Case meet most applications on board cargo vessels as well as naval vessels and mobile Offshore Drilling Units refer to pressure and temperature. Our Mini system makes it easy to adjust to the specific needs you might have on certain vessels for pressure and temperature. All test cases come complete with necessary accessories.
