East African Green Hull Cleaner


HullWiper Ltd has launched their first East African hull cleaning solution in partnership with underwater hull cleaning specialist, Immersub. The introduction of a safe and green hull cleaning solution supports the Mauritius Ports Authority ‘Green Port Concept’ for sustainable and eco-friendly port activities.

HullWiper’s patented Remotely Operated Vehicle (ROV) system uses adjustable seawater jets under variable pressure to remove fouling, instead of brushes or abrasives, minimising the risk of damage to expensive anti-fouling coatings. No divers are used, so there is no risk to human life and cleaning can be conducted day or night, in most weather conditions, and whilst cargo operations are underway. Removed residues are collected by an onboard filter and deposited into dedicated drums onshore for locally-approved environmental disposal. The filter also reduces the risk of cross-pollination of waters with alien species. HullWiper Ltd., Immersub


Seatooth PipeLogger WFS


NjordGuard™ is an integrated protection system designed and developed to protect offshore windfarm power cables in wind turbine generators and offshore substation platforms. It is easily assembled on a vessel to allow speedy installation, while it’s highly abrasion resistant API 17L certified Uraduct material enables it to travel over the seabed without damage, extending cable life. Most importantly, it facilitates installation, reuse, and removal without diver and ROV intervention, optimizing efficiency and maximizing safety.

It requires only minimal assembly. The primary external dual stiffener is factory cast directly onto the connector. And the internal stiffener can be supplied pre-assembled. Only the external tail needs to be attached with Trelleborg’s novel connection system. Trelleborg Offshore.


Power for Complex Electronics


WhisperPower has introduced the Supreme Pro battery charger series to meet increasing demands from the shipping industry for DC voltage stability, interference suppression and system integration with navigation and communication systems.

The Supreme Pro three-stage battery chargers feature 3 separate DC outputs for charging multiple battery banks and are suitable for any type of battery including Lithium batteries. Different charging protocols can be set via a DIP switch, laptop or USB interface.

They comprise of four 24-V chargers with charging powers of 40, 60, 80 or 100 amps, respectively, and universal auto-ranging input (90 to 265 V AC, 50 to 60 Hz). The charger can easily be connected to external analog or digital control panels. WhisperPower.



Measurement and Simulation

A 12-channel benchtop synchro/ LVDT simulation/acquisition module, the P545 is a DSP-based measurement and simulation instrument for synchro, resolver, RVDT- and LVDT-type magnetic rotation and position sensors. It provides 12 independent, isolated i/o channels. Highland Technology Inc.

Side Scan Sonar Software

SonarWiz 7.4 includes more than 80 new features and fixes. Key enhancements include: automated post-processing for side scan data, sub-bottom data aggregation function and improved batch contact import system. Chesapeake Technology Inc.

USV for Chinese Market

Nortek China has introduced an open, low-cost platform to measure water current and direction, with integrated Doppler instrumentation for ocean surveying. The USV has an industrial personal computer as the main operating platform and uses Remote Desktop to communicate with all instruments. Nortek Group.

Maritime Surveillance

The TORNADO-ER, a panoramic IR scanning and automatic maritime target detection and tracking system, was designed for coastal and maritime wide-area surveillance, coastal protection and maritime traffic control, especially in crowded maritime areas. It can track a large number of targets simultaneously in real time. CONTROP Precision Technologies Ltd.

Digital Video Solution

Eagle Portable enhances the live feed from a camera in any existing SDI video system and suits poor-visibility conditions. It connects between the camera and a monitor or VCR for simple installation and can be controlled remotely through a standard RS232 serial interface with simple text commands. The Eagle Integration kit contains all the necessary parts for simple plug-and-play integration. LYYN AB.

Acoustic Modem Location

There is a new GPS option for the UTS-9000 series Universal Topside Units used to command a line of acoustic modems and releases. Customers can upgrade existing UTS-9400 units, or order this option on new systems. The new feature allows them to survey in, and record, precisely where their acoustic releases and/or modems are deployed using only the topside unit and a dunking transducer. Teledyne Benthos.

Future-Proof Antenna

v150NX is a 1.5-m Ku to Ka convertible VSAT supporting 2.5-GHz wide Ka-band networks and geostationary, medium and low Earth orbit constellations. Intellian Technologies Inc.

Subsea Drilling Winch

The Passive Heave Compensation Winch system is a set of winches that safely provide constant tension through the rated range of motion. It is applicable to any environment where a load experiences resistance to movement due to hydrodynamic drag. Logan Industries International Corp.

Mini Optical Gauge

Part of the FiberLine Intervention (FLI) system, the miniature optical pressure-temperature gauge widens the well surveillance application envelope for FLI, both on and offshore, and offers operators a low-cost and disposable alternative to permanent downhole sensors and more traditional electronic logging devices. Well-SENSE Technology Ltd.

Fiber-Rope Offshore Crane

FibreTrac is able to exploit its full lifting capacity because fiber rope weighs virtually nothing in water, so no additional load is experienced by the crane, regardless of the length of rope, in contrast to steel wire-rope cranes. FibreTrac has a 150-t safe working load capacity and features an advanced rope monitoring and management system. MacGregor.

Camera Housing

FA6500 V2 housing is intended for the Sony a6500 and a6300 mirrorless cameras. V2 features the Fantasea Hybrid Vacuum Safety System, which includes both a pre-dive vacuum check and an on-dive leak detector. Fantasea Line.

Underwater Defense Sonar

PointShield is a portable diver detection sonar for the protection of surface vessels from underwater intrusion and sabotage. AquaShield diver detection sonar provides permanent underwater security for all types of underwater threats. DSIT Solutions Ltd.

GPS Antenna

Connected wirelessly to the ZigBoat system, the ZB211 delivers push notifications on fleet tracking, geofencing, weather forecasts and anchor watch. Glomex Marine Antennas USA Corp.

Marine Nav App

iNavX now provides access to Delius Klasing’s detailed digital charts for European inland waterways and sea charts. iNavX.

Wave-Actuated Profiler

Prawler spans the surface to 500 m and is suitable for the energetic open ocean to low-wave freshwater lakes and reservoirs. It is a low-cost, lightweight alternative to distributed sensors. Deployments of 20 profiles per day for 12 months are possible. McLane Research Laboratories Inc.

Subsea Connectivity

The Hydro Rubber Moulded (HRM) series of subsea connectors come in a range of combinations, sizes and voltages. There are five variants on offer: from bulkheads, attachables and inlines to overmolds and dummy plugs. Hydro Group plc.

Pressure Loggers

The RBRquartz³ Q and RBRquartz³ BPR use the Paros Digiquartz pressure sensor to provide long-term pressure measurements with high stability and resolution. RBR Ltd.
