Minister of Transport promulgates Circular on inland waterway survey.

Chapter I

GENERAL PROVISIONS

Article 1. Scope

This Circular prescribes inland waterway survey.

Article 2. Regulated entities

This Circular applies to organizations and individuals related to inland waterway survey operation.

Article 3. Definition

In this Circular, terms below are construed as follows:

1. “width of inland waterway” is measured at the bottom of the inland waterway based on the cross section of the inland waterway in question and based on technical level of current conditions of inland waterways.

2. “inland waterway route” refers to one or multiple inland waterways whose starting point and ending point are determined specifically.

Chapter II

INLAND WATERWAY SURVEY

Article 4. Classification of inland waterway survey

1. Regular inland waterway survey refers to surveys conducted during regular inspection of inland waterways.

2. Periodic inland waterway survey refers to survey of inland waterway conducted with a determined frequency.

3. Irregular inland waterway survey refers to survey conducted when any irregularity occurs within the inland waterway or protective corridor of inland waterway that can cause loss of safety to inland waterway traffic.

Article 5. Range of survey and scale of inland waterway topographic map

1. Range of inland waterway survey

a) Regular inland waterway survey shall be conducted within the waterway (based on the centerline of the waterway) and shoals mentioned under inland waterway management dossiers;

b) Periodic inland waterway survey shall be conducted within the width of inland waterway and both sides of inland waterway protective corridor towards the bank of the river, channel, canal, lagoon, gulf;

c) Irregular inland waterway survey shall be conducted in the area where the irregularity occurs within the inland waterway and protective corridor of inland waterway. In case of any irregularity that creates new inland waterway, surveying width shall not exceed 3 times the width of the new waterway and not exceed the bank of the river, channel, canal, lagoon, gulf. Length of survey shall be the length of the new inland waterway.

2. Scale of inland waterway survey topographic map

a) Scales of topographic map serving the purpose of inland waterway survey consists of 1:1.000; 1:2.000 and 1:5.000;

b) Topographic map scale of 1:1.000 applies to irregular inland waterway survey. In case an irregularity creates a new inland waterway, scale of topographic map depending on surveying width shall comply with Point c, Point d, and Point dd of this Clause;

c) Topographic map scale of 1:1.000 applies to up to 50 m of surveying width;

d) Topographic map of 1:2.000 applies to surveying width that ranges from more than 50 m to 300 m;

dd) Topographic map scale of 1:5.000 applies to surveying width of more than 300 m.

Article 6. Frequency of periodic inland waterway survey

1. Frequency of periodic survey of national inland waterway shall be determined based on:

a) Type of inland waterway serving management purposes;

b) Role of inland waterway in inland waterway transport;

c) Load capacity of watercrafts operating along inland waterway;

d) Technical grade of inland waterway.

2. Frequency of periodic survey of national inland waterway shall be determined by scoring. A scale of 100 scores shall be used for assessment and determined based on criteria under Appendix attached hereto.

3. Frequency of periodic survey of national inland waterway includes:

a) A frequency of 1 year per survey for waterways with a total score of 85 or higher;

b) A frequency of 3 years per survey for waterways with a total score ranging from 70 to below 85;

c) A frequency of 5 year per survey for waterways with total score of below 70;

d) A frequency of more than 5 years per survey for national waterways whose total scores are mentioned under Point a, Point b, or Point c of this Clause but are situated in lake, lagoon, gulf, channel, canals with great depth according to decision of Ministry of Transport at request of Vietnam Inland Waterway Administration.

dd) A frequency of less than 1 year per survey for waterways, routes of waterway of other countries at estuaries or areas heavily deposited or eroded. Vietnam Inland Waterway Administration shall rely on the nature, scale, range, and role of an inland waterway to inland waterway transport to request Ministry of Transport to decide on survey frequency.

4. In case of provincial inland waterways, on the basis of criteria under Clause 1 of this Article, Departments of Transport shall request People‘s Committees of provinces to decide on frequency of periodic survey of provincial inland waterways.

5. In case of special-use inland waterways, organizations and individuals owning special-use inland waterways shall decide on surveying frequency without exceeding 5 years per survey.

6. In case of inland port waters, Vietnam Inland Waterway Administration and Departments of Transport, within their management authority, shall decide on survey frequency of inland port waters no more than 5 years per survey and direct inland port authorities to survey inland port waters in order to ensure safety for watercrafts.

7. Once every 5 years in the 3^rd Quarter of the last year or whenever necessary, Vietnam Inland Waterway Administration shall update, revise, consolidate, and request Ministry of Transport to publish list of national inland waterways subject to periodic survey for the next 5-year period. Documents presenting the list of inland waterways subject to survey include:

a) Written request for publishing list of inland waterways subject to survey;

b) List of inland waterway subject to survey, including: name of waterway (route), topographic map scale, survey frequency;

c) Assessment and scoring results which determine surveying frequency in accordance with Clause 3 of this Article;
