NG Supplies Nav Systems for Brazil OSVs

Northrop Grumman Corporation's (NYSE:NOC) Sperry Marine business unit has been awarded contracts to supply bridge navigation systems for four new offshore supply vessels to be built in Brazil. The four multipurpose platform supply vessels, designed by Rolls-Royce, will be built at the Estaleiro Alianca shipyard near Rio de Janeiro for Companhia Brasileira de Offshore (CBO). They will be placed on long-term charter with Petrobras, the Brazilian state oil company, to provide support services for offshore oil platforms. The scope of supply includes radars, autopilot, speed and heading sensors and other navigation systems. Sperry Marine's sales and service representative in Brazil, Vision Marine Ltda, will be responsible for installation, commissioning and servicing the equipment on the vessels. Last year, Sperry Marine received orders to supply the same navigation packages for four similar vessels at the same shipyard.

Keeping a Watchful Eye

Maritime surveillance technique & technology in the new millennium In 2014, Forbes Associate Director for Maritime Services at Control Risks stated that maritime risks are on the rise. Mariners and ship owner/operators experienced a 26% spike in maritime piracy and armed robbery since 2014  and the North Sea Oil Industry admitted that it had been targeted and thwarted cyber attacks, attacks that if successful could have caused untold financial and logistical damage

TT Club Urges Quay Crane Anti-Collision Systems

The TT Club is urging container terminal operators to fit electronic sensor devices to quay crane booms to prevent them accidentally colliding with vessels during loading and unloading operations in port. The TT Club says that crane booms colliding with the structure or equipment of a ship is an all-to-common occurrence at almost every port around the world, causing serious injuries to workers and costly repairs and operational downtime.

How to Calibrate an AC-operated LVDT Linear Position Sensor

LVC-4000 (Photo: Macro Sensors)

Calibration is necessary before the installation of an AC- operated linear position sensor to ensure accuracy. Calibration corrects any slight variances between sensors, helping to improve repeatability. Because of the linearity of LVDT Sensor output, a simple two-point calibration is simple. Two points should be as far apart as possible, but within the linear range of the LVDT Linear Position Sensor and preferable within the measurement range in which it will be used.

Macro Sensors Gauge Tank Volume Changes

This diagram shows the LVDT level sensor attached to the side of a tank using a flat-hook assembly. The high-permeability core follows the position of the stainless-steel float. The LVDT electronics sense the core position using magnetic induction. Output is a 4 to 20-mA instrumentation current loop corresponding to the position of the core in the LVDT body.

Configured with a float, Macro Sensors HSIR Series LVDT Linear Position Transmitters are serving as level sensors to measure liquid level changes from a few inches to several feet in gauging tank level volumes. In this LVDT level sensor configuration, a stainless-steel float coupled to a nonmagnetic stainless-steel rod is attached to the high-permeability, armature core of the LVDT. The 4 to 20-mA loop-powered LVDT position transmitter senses the position of the core and, therefore

Monitoring for Efficiency, Safety

“... since the monitoring network was installed, we have recorded a sudden drop in temperature of 8°C in just 5 minutes at the port of Armadale on the Isle of Skye, and a maximum wind gust of 96 knots at Castlebay on the Isle of Barra.”

Ferry masters operating off the west coast of Scotland traditionally would have to sail to a port and on arrival visually assess the weather and tide conditions before deciding whether it was safe to berth alongside the pier or quayside: a process which wasted time and fuel
