Odd Callers

Odd Caller 1
We rarely see crude oil tankers in Halifax anymore since there are no refineries here. A crude tanker, even in ballast is therefore an odd sight these days. Seaways Hatteras arrived in ballast this morning from Canaport, off Saint John and went to anchor.

The ship dates from 2017 when it was built by Hyundai, Samho. Measuring 81,433 gt and 158,432 dwt and is classed as a Suezmax . It is managed by International Seaways Corp of the USA, along with forty or so tankers of various sizes. The company is a free-standing spin-off of OSG (Overseas Shipholding Group) independently listed on the NYSE as of December 2016.

With only decommissioning work underway offshore these days, it is unusual to see specialist marine construction ships. Adhémar de Saint-Venant  sailed from pier 27 today after a brief port stay.

Built in 2017 by AVIC Weihai Shipyard Co, it is a 7531 gt, 6424 dwt ship used to bury offshore pipelines. It carries the rock aggregate in its hold and deposits the material by means of a "fall pipe" - a large diameter black tube. It works to precise location using a sophisticated Level 2 Dynamic Positioning system. 

Owned by the Belgian marine construction company Jan de Nul, it is registered in Luxembourg and named for Adhémar Jean Claude Barré de Saint-Venant (1797-1896) a French mathematician who pioneered hydraulic engineering. A sister ship is named for the better known Daniel Bernoulli.

The ship has apparently completed whatever work it was doing and is headed for Zeebrugge.

The Jan de Nul company has been working on the offshore wind project off Virginia Beach and its installation ship Vole au Vent is due back tomorrow.
