A World First for Hydrographic Surveying Certification

The Australasian Hydrographic Surveyors Certification Panel (AHSCP) is the first national/regional competency certification scheme to be internationally recognised. On 24 May 2012, at its annual meeting held in Buenos Aires, Argentina, the FIG/IHO/ICA International Board for Standards of Competence for Hydrographic Surveyors and Nautical Cartographers (IBSC) awarded recognition to the AHSCP Certification Scheme. This was indeed a historic event for the AHSCP, being the first and currently the only national/regional hydrographic surveyor competency certification scheme to gain recognition from the IBSC.     by Commodore Brett Brace RAN, Chairman AHSCP   In general terms IHO 'Category A' or 'Category B'...

Minimising Offshore Survey Product Liability

In this article, offshore survey products are meant in the broadest sense. Not just survey, navigation and positioning, but the purpose or project that the dependent results are used for. No work in the offshore industry can proceed efficiently without good positioning data and survey information. From the initial 2D and eventual 3D surveys, through to the commissioning of the offshore installation and pipelines, offshore survey is the link between the various pieces of the complex puzzle. In this article, offshore survey products are meant in the broadest sense. Not just survey, navigation and positioning, but the purpose or project... (read more)

Forward Looking Sonar for Navigation

Safer Navigation with Wider Adoption of FLS
An increasing number of ships are venturing into areas where the only hydrographic data available do not meet the standard many of these vessels require for safe navigation. A number of recent and some not so recent marine casualties have resulted from encounters with uncharted, isolated seabed features (Russell, 2014). The situation is recognised by the IHO; but the necessary improvement to the hydrographic data will take years. Meanwhile, the informed use of Forward Looking Sonar (FLS) could contribute to safer navigation in inadequately charted areas. Present-day commercial FLS developed from its use by fishing vessels and for obstacle avoidance... (read more)

‘Killer’ AUV Sonar System

In January 2001, C&C Technologies (C&C), a company based in Lafayette (Louisiana, USA), introduced the first commercially successful autonomous underwater vehicle (AUV) to the offshore industry. The AUV’s survey sensor suite, which included an EdgeTech side-scan sonar and sub-bottom profiler, performed well in the Gulf of Mexico and Brazilian offshore environments. However, West Africa proved more challenging – particularly for the sub-bottom profiler. C&C soon began searching for alternative technologies to provide better sub-bottom profiler penetration and higher resolution side-scan sonar imaging.Jim Chance, C&C Technologies (USA) Art Kleiner, EdgeTech (USA)<P> Narrator: Fast forward to the early autumn of 2004… C&C...

Market Prospects for AUVs

This article is based on the results of a new studyThe AUV Gamechanger Report 2008-2017published by Douglas-Westwood Ltd. This report aims to consider the prospects for this game-changing technology and value the future markets for AUV manufacturers to 2017.<P> Un-tethered Autonomous Under­water Vehicles (AUVs) have the potential to change the game in many areas of underwater oper­ations. Long an area of research, AUVs are beginning to show their abilities as cost-effect­ive tools in applications ranging from deep-water survey for the offshore oil and gas industry to military oper­ations. The growing need for many facets of ocean observation also offers great... (read more)

Supply Hydrographic Personnel

Hydro INTERNATIONAL Interviews Johan Stam, Business Development Manager, Atlas Services Group
There is a global shortage of hydrographic surveyors. The industry is faced with an interesting challenge and looks to specialised education facilities and personnel suppliers to assist in solving this problem. Even in times of high unemployment it can be difficult to find sufficient skilled personnel to carry out hydrographic survey work in the offshore environment. Hydrographic educational institutions around the world are struggling to attract enough students, resulting in noticeable shortages of trainees within the survey departments of large and small survey contracting companies. Although working conditions have improved considerably over recent decades, the environment in which hydrographic surveyors... (read more)

Study the Basics and Ask for Support

Hydro International Interviews Antti Castrén
Hydrographic mapping is all about collecting and processing data that leads  to products such as nautical charts and other products contributing to safe navigation, a better environment and secure constructions offshore. The quality of the data is important  and this is where the IHO steps in and facilitates standards for acquisition and presentation. Hydro International interviews Antti Castrén, project manager at the Finnish Transport Agency and chairman of the IHO Data Quality Working Group (DQWG). He touches international aspects of data quality in general, opportunities available for many Hydrographic Offices as well as hydrographic challenges in the Baltic.  Why did... (read more)

“How to Sustainably Use and Protect Oceans and Coasts”

Hydro International Interviews Dr Walter Cruickshank, Acting Director, BOEM
During the recent Offshore Technology Conference in Houston, Texas, USA, the Executive Order on Implementing an America-First Offshore Energy Strategy was signed to support offshore science development. In the context of the highly dynamic offshore energy sector, 'Hydro International' interviewed Dr Walter Cruickshank, acting director of the Bureau of Ocean Energy Management (BOEM), about accelerating authorisations for seismic surveying, marine geospatial data, environmental monitoring and the potential of marine renewable energy. What is the role of maritime geospatial data for BOEM? BOEM uses maritime geospatial data for a variety of needs. For example, by identifying ocean areas used for various... (read more)

Government and Private Surveying Working Together

Hydro International Interviews Captain Nuhu Jidere Bala, Hydrographer of the Nigerian Navy
Nigeria is a country that plays an important role for the African continent, even though this is not at all times apparent. It has quite a lot of offshore activity and its ports handled 22,324,223 million metric tonnes of cargo in the first nine months of 2014. Improving the waterways is one of the goals the management has set itself. Add to this all the inland waterways that have an economic significance as well. This makes it interesting to talk to Captain Nuhu Jidere Bala, Hydrographer of Nigeria. Nigeria has almost one thousand kilometres of coastline and eight thousand kilometres... (read more)

Quality ENC Production for HOs

The challenges facing the contractor
Hydrographic Offices (HOs) all over the world are going digital in their production environment. New shipboard equipment and improved display techniques embrace all the latest technologies in the interests of ensuring the Safety of Life at Sea (SOLAS). HOs increasingly seek to produce and distribute ENCs to standards specified in IHO Special Publication S57 (edition 3.1). The production and validation of ENC datasets to achieve these stringent quality requirements are outlined here. The International Maritime Organization (IMO) has amended SOLAS articles relating to carriage requirements for the use of ECDIS in certain types of vessels. When production is outsourced manufacturers... (read more)
