Glossary

Ballast water

Ballast water in ships is used to improve depth, stability and strength in case the ship is not fully loaded.

Building with Nature

Innovation program focused on the development of new design concepts for river, coastal and delta areas. The aim of the program is to investigate the best approach to strengthen the interaction between human activities and nature.

Cashflow

Group net profit adjusted for depreciation, amortization and impairments.

CO2

Carbon dioxide is an odorless and colorless gas and exists in the Earth’s atmosphere. Carbon dioxide is a greenhouse gas (source Wikipedia).

Cutter suction dredger

A ship that dredges while being held into place using spuds and anchors. This technique combines powerful cutting with suction dredging. Cutter suction dredgers are mainly used where the bed is hard and compact. The dredged material is loaded into hoppers but is generally pumped to land through a pressure pipeline.

EBITDA

Group earnings before the result of associated companies, interest, tax, depreciation, amortization and impairments.

Fallpipe vessel

Vessel that moves over the area to be covered, while dumping the stones on board through a fallpipe. The vessel is kept in place by a dynamic positioning system in which the propellers and rudders are controlled by an automatic system. The end of the pipe is located just a few meters above the level of the surface to be covered. The fallpipe is controlled using a precise positioning system. The fallpipe vessel Seahorse can also be equipped with an A-frame on the aftship and a grab controlled by an ROV (Remotely Operated Vehicle). This makes it possible to dredge down to depths of 1,000 meters.

GRI

Global Reporting Initiative. An international organization that develops global standards for annual social reporting. The aim of GRI is to make sustainability reporting as routine and comparable as financial reporting for all organizations – regardless of size, industry or location.

HFO

Heavy Fuel Oil.

Home market

Boskalis distinguishes itself from its competitors by the use of a home market strategy. The home market organizations have local marketing profiles, as well as their own fleet and infrastructures.

The ISM-code requires ship managers to implement and maintain a safety management system.

ISO standard

Standards of the International Organization for Standardization; the global federation of national normalization organizations that issues standard requirements for, amongst other things, quality management systems (ISO-9001) and environmental management systems (ISO-14001).

LTIF

Lost Time Injury Frequency. Expresses the number of workplace accidents serious enough to result in absence from work, per 200,000 hours worked.

MDO/MGO

Marine Diesel Oil/Marine Gas Oil.

SHE-Q

Safety, Health, Environment-Quality

Trailing suction hopper dredger

A self-propelled unit that loads its well or hopper using centrifugal pumps and pipes that trail over the bed as the ship sails. Trailing suction hopper dredgers can operate independently of other equipment and can transport material over long distances. The dredged material is dumped through flaps or bottom doors, by rainbowing, or pumped onto land using a pipeline.
